Embodiment 1

[0047] Embodiment 1: D-pinitol promotes germination and growth test of Panax notoginseng seeds

[0048] This test adopts the method of sand-cultured Panax notoginseng in bottles, and adopts analytical-grade purity D-pinitol as the experimental material. First, 1 g of D-pinitol is added to 1 L of sterile water to prepare a 1000 mg / L mother liquor, and then gradually diluted to The solutions of 1, 5, 20, and 50 mg / L were used for later use, and sterile water was used as a control treatment; 100 g of sterilized quartz sand was placed in a glass tissue culture bottle and then dried in an oven at 141 ° C for 4 h to sterilize. After cooling, add 18ml of D-pinitol solution with a concentration of 0, 1, 5, 20, and 50mg / L respectively, stir evenly, and plant 12 Panax notoginseng seeds. On the 60th day, start to investigate the emergence of the seedlings, and investigate the fresh weight index of the Panax notoginseng single plant on the 90th day. The test results are shown in figure ...

Embodiment 2

[0050] Embodiment 2: D-pinitol treatment continuous cropping soil bottle planting test of Panax notoginseng

[0051] The method of using potted continuous cropping soil for long-term watering: the notoginseng continuous cropping soil is taken from the notoginseng farmland in Wenshan, Yunnan, and the retrieved continuous cropping soil is dried in the shade, then passed through a 40-mesh sieve to remove plant residues in the soil, and weigh 2.5 kg The continuous cropping soil was added to the finishing box (28×20×17cm) for later use; 1g of analytically pure D-pinitol was added to 1L of sterile water to prepare a 1000mg / L mother solution, and then gradually diluted to 1, 10, 50, 100mg / L solution, with sterile water as the control treatment; take 500ml of the above solution and add it into different finishing boxes, then cover the lid of the finishing box, and seal it with parafilm, and place the finishing box in a cool place away from light. Set up 3 replicates (eg figure 2 sh...

Embodiment 3

[0053] Embodiment 3: D-pinitol induces resistance test to Panax notoginseng

[0054] The method of spraying treatment with D-pinitol: place the potted plants of Panax notoginseng after transplanting and surviving in a transparent plastic airtight incubator, transplant 10 plants of Panax notoginseng in each pot, and use sterile water and D-pinitol at a concentration of 1mg / L respectively. - Pinitol sprayed the potted Panax notoginseng, treated with sterile water as the control group, and D-pinitol as the treatment group; the leaves were sprayed with the above liquid every day, after 5 days of continuous treatment, the leaves were challenged to inoculate Panax notoginseng black Bacteria cake of Alternaria panax, after inoculation, moved to a transparent plastic incubator for moisture cultivation, collected diseased leaves 3 days after inoculation, used Epson Perfection V850 Pro scanner to scan diseased leaves, and used Adobe Photoshop software to intercept and calculate The rela...

Abstract

The invention discloses the application of D-pinitol in promoting the growth of Panax notoginseng and inducing resistance. The present invention finds that using D-pinitol to pre-treat the Panax notoginseng planting carrier can not only promote the germination and growth of Panax notoginseng seeds, increase the fresh weight of a single plant, but also improve stress resistance; spray D-pinitol on the Panax notoginseng plant , can induce the resistance of Panax notoginseng. Since D-pinitol widely exists in pine needles, it is a plant-derived conditioner that can be degraded by nature and will not cause environmental pollution, so it can be widely used in the cultivation of Panax notoginseng.

Description

technical field [0001] The invention relates to the technical field of Panax notoginseng planting, in particular, the invention relates to the application of D-pinitol in promoting the growth of Panax notoginseng and inducing resistance. Background technique [0002] Sanqi (Panax notoginseng (Burk.) F.H.Chen), also known as Tianqi, Dianqi, Shensanqi, Hansanqi, etc., is a perennial herbaceous Umbelliferae Araliaceae plant of the genus Ginseng, which has the functions of stopping bleeding, dissipating blood stasis, relieving pain and eliminating pain. It has good effects such as swollen and so on, and its tubers and flowers are mainly used as medicine (National Pharmacopoeia Commission, 2015; "National Compilation of Chinese Herbal Medicine (Third Edition)", 2014). The pharmacological components of Panax notoginseng are complex, and it has the functions of hemostasis, blood circulation, antithrombotic, anti-inflammatory, liver and liver protection, myocardial protection and an...
